Wiseco Chevy LT1 4.075in Bore 1.105in CH -6.90 CC Piston Set

This Wiseco piston set includes eight forged pistons, designed specifically for Chevrolet LT1 engines. Each piston features a 4.075-inch bore and a -6.90cc dish volume, with a compression height of 1.105 inches and a 0.927-inch pin diameter. These are serious components built for demanding race applications where durability and performance are critical.

Crafted from 2618 aluminum in the USA, these pistons are forged and machined for improved tensile strength. They come with precision ring grooves, an anti-detonation groove, and features designed for additional ring seal. The fully machined crown and forced pin oiling further enhance their ability to handle heavy to severe duty use. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation.

If you're building a high-performance LT1 engine for racing, these pistons are a solid option. Keep in mind that these are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all necessary supporting components and refer to manufacturer instructions for proper installation.
